Benefits of technology

The patent text discusses a method for making a hearing device with a shark skin surface structure. The method allows for the scales on the device to be aligned parallel to the direction of wind speed, which improves the device's ability to withstand wind. The shark skin structure is applied to the hearing device using adhesion or injection molding methods. These methods can produce hearing device housings or hooks with the shark skin structure quickly and affordably. The hard or hardened surface of the device provides a stable structure that can withstand wear and tear. The technical effect of this patent is to improve the durability and functionality of hearing devices in windy or other outdoor environments.

Problems solved by technology

If this swirling appears in the region of the microphones and / or the microphone inlet openings of a hearing device, they produce noise which can be perceived as bothersome by a hearing device wearer, or the one possible wanted signal, i.e. speech, is overlayed and the perception of the wanted signal is negatively influenced.

Embodiment Construction

[0032]Referring now to the figures of the drawing in detail and first, particularly, to FIG. 1 thereof, there is shown a schematic representation of a behind-the-ear hearing device 1′ according to the prior art. The device has several functional parts, including a housing 2′ to be worn behind the auricle 15′ of a hearing device wearer. Aside from electronic components which are combined to form a signal processing unit 13′, two microphones with the microphone openings 4′, a battery 10′ and a receiver 12′ are arranged in the housing 2′. The acoustic signal generated by the receiver 12′ is guided through a hearing device hook 5′ and an acoustic tube 14′ to an earpiece 11′, which is inserted into an auditory canal 16′ of the hearing device wearer. When the hearing device is being worn, the straight line of sight of the hearing device wearer defines an axis 21, whereby the line of sight in FIG. 1 is also specified by an arrow.

Abstract

A hearing device has reduced acoustic wind sensitivity. For that purpose, the hearing device has a surface formed with a shark skin structure.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priority, under 35 U.S.C. §119, of German patent application DE 10 2011 006 563.6, filed Mar. 31, 2011; the prior application is herewith incorporated by reference in its entirety.BACKGROUND OF THE INVENTIONField of the Invention[0002]The present invention relates to a hearing device with reduced acoustic wind sensitivity.[0003]Hearing devices are used to supply hearing-impaired persons with acoustic ambient signals which are processed and amplified to compensate for and / or treat the respective hearing impairment. A hearing device includes in principle one or more input converters, a signal processing facility with an amplification facility and / or an amplifier and an output converter. The input converter is generally a receiving transducer, e.g. a microphone and / or an electromagnetic receiver, such as an induction coil. The output converter is generally implemented as an electroacoustic converter, e.g. miniature...
